The four factors that affect climate are latitude, elevation,  distance to large bodies of water, and ocean currents.IN few cases  the greenery also effects the climate.
Because of the arid nature of the region, some sectors will be particularly affected by climate change. The impacts on these sectors are summarized below. Ecological systems: The region is mostly arid and semi-arid and is dominated by grasslands, rangelands, deserts, and some woodlands. Vegetation models project little change in most arid (or desert) vegetation types under climate change projections.
